Thy Will Be Done by Alexander Marsh

Created by: Alexander Marsh

Thy Will Be Done is a captivating mentalism trick that revolves around a single tarot card and three everyday objects: a watch, a pen, and a coin. The spectator freely interacts with these objects, setting the time on the watch and choosing which items to keep, give to the magician, or leave on the table. The tarot card, revealed at the end, eerily mirrors these choices, including the exact time the spectator set on the watch. This creates a powerful illusion of free will and prediction, making it perfect for close-up or parlour magic. Buyers should note that an analog watch (not included) is required for the full effect.

Effect

"Thy Will Be Done" by Alexander Marsh is a mentalism trick that creates the illusion of free will. A spectator interacts with three objects—a watch, a pen, and a coin—making choices that feel entirely their own. The magician then reveals a tarot card that mysteriously reflects the spectator’s decisions, including the exact time they set on the watch. The effect is strong, leaving the audience with a sense of eerie coincidence or supernatural insight.

Full details

The trick includes two tarot cards—one standard tarot size and one poker size—both featuring the same design. The cards depict a magician with symbolic objects (watch, pen, coin) that mirror the real-world items used in the performance. The spectator freely chooses which objects they keep, which the magician takes, and which remains on the table. The tarot card then reveals these choices, with an added kicker: the time shown on the card matches the time the spectator set on the watch.

A 37-minute tutorial video explains the method, covering all possible outcomes and performance tips. The trick requires an analog watch (not included), but any inexpensive watch with a date function will work.
